e Our invention Vrelates to Vimproveinents in shower-*bath brushes, and more particularly to couplings or connections between therigid discharge tube and the'fleXible supply'ztube with which such brushes are provided, 'or which may be said to form Vparts of'such brushes, and consists essentially of a peculiar- Y ly constructed bushing permanently aliixed tothe inlet terminal of the 'discharge tubey of such a brush, and a nipple capable of being attached to the discharge terminal of a supply tube of such a brush, said bushing and nipple; being adapted for screw-threadedy Ven-z f i gagement with each other, together with suchr other .parts and' members-asV may be necessary or desirable in order to renderthe ,connec- Vtion 'complete and serviceable*in-,every'ree f spect, all as hereinafter set forth. A'

-.Heretofore it has been customaryv to ati 20. tach a nipple permanently tov'one end of the rigid discharge pipe of a shower-bathV brush,

and to force one terminal of the flexible sup-v ply tube, Vof said brush, Yonto and into engage@ p ment with such nipple, and the reenforcing 2'5and`pr'otecting spring at one terminal over'Y v v'and onto the portionof said inlet tubewhich embraces Vvthe nipple. This construction and` arrangement make it very inconvenient to.

L, disconnect the supplyVv tube fromfthe 'dis-- charge 'tube'and againfconnect it therewith,l operations which are required moreorless frequently; and'such construction vand ar'-` rangement also are 'responsible forv injury to and wear of the terminal portion -of thel inlet tube which is attached to the nipple, in proportion to the frequencytof the connecting and disconnecting operations. The vprimary obj ect of our invention is, therefore, to overa come the above-noted ,objections and diff* 7 40 ficulties, whichA we do `by providing the i Y shower-bathlOIuSh with a connection of such a characterl that isl capable of being easily and quickly disengaged, the oneypart from: V e i the other, Vand as easilyand quickly engagedor coupled'together, the onepart to the other. 1

'Our connection necessarily r-endersthe brush very much more'convenient, and prolongs the Vlife of the supply tube. y i

The discharge tube, Vof a brush of this "507' character, is usually made of material which exterior flange bushing ofmaterial such as Celluloid, and an interiorvbushing of material suchas metal, the two bushings being permanently united, and said inner bushing being internally screw-threaded to "receive an eX'- ternally screw-threaded part ofan associated nipple.

let tube, with the ange of said bushing covering rthe ledge rportion of said inlet end, and

'permanently secured to said tube.

Other objects and advantages will appear in the course ofthe following description.

Weattain the obj'ectsand secure the advantages'of our inventiongby the means'illustrated in rthe accompanying drawings, y in which- Figure `1 is a side of our'invention, that is ytolsay, of the connection Vbetween the inlet and outlet tubes y'of the brush; Fig. 2, an enlarged, top plan of y kThe combination bushing thus formed is inserted in the inlet end of the outelevation of a' shower-' V 'Y Vbath brush which vembodies la practical form' the combination bushing ofsaidconnection;

F ig. 3, an enlarged, verticalsection throughA said combination'bushing and aportion of the outlettube in which andto whichl said bushy ingis permanentlyattachedyand, Fig. 4:, anV 1 enlarged, vertical Sectionlthrough the'nipe ple of said connection and attached portionsof the supply tube and reenforcingspring.

Similar reference characters designate similar parts throughout theseveralviews.' f l The shower-bath brush, illustrated in conforateddischarge tube 2,7a` brush 3, -an inlet vtube 4, and a Asupporting andreenforcing spring. The brush, "which `is of loopy formation, is secured to the handle l and pro# jects above or beyond the saine- V The tube 2; is open' atthe bottom`or inner end,'is affixed nection herewith, comprises a handlel, a perl fto the handle l and extends through'said handle into the opening in the loop of the brush 3, and has perforations in the sides of that portion of said tube which is in said opening. Cnly a portion of the supply tube 4 is shown. This tube is adapted to have one end connected with a faucet or other watersupply lixture, and the spring 5, which is of the spiral type, encircles said tube'adjacent to the other end thereof, and is for the customary purpose of preventing the tubefroin making too sharp a bend at and adj acent its point of connection with the tube 2, and thus supports, reenforces, and prolongs the life of sait first-named tube. Both structurally and functionally all of these parts and mem-` bers are old and Well known. l

The inner-ciid portion of the tube 2 is provided with a reenforcing, strengthening, and protecting, and coupling, combination bushing, which consists of an inner bushing 6, preferably of metal, and an outer bushing 7 of Celluloid or more or less similar materia-l,

Vsaid inner and outer bushings being perinanently united tormake up said combination bushing. The combination bushing or Vthe bushing 7 thereof lits the inside of the tube 2, and is rigidly and permanently attached to said tube. At the exposed terminal of the bushing 7 is an integral flange 8 that is in Contact with the contiguous end-edge portion of the tube 2.

rThus it is seen that the combination bushing reeiiforces and strengthens the end ofthe tube 2 where said tube is'subjected to strain from the tube 4, and at the same time affords for the tube 4, said nipplefhavinglat one end a screw-threaded projection l adapted to lit into the Vscrew-.threaded bushing 6, and at the other terminal a shouldered part 1l to be received insaid tube at the terminal op` posite that which is adapted `to be attached to the faucet or other fixture. The nipple `9 also has a flange 12, between themain part of' said nipple and the projection l0, to-abut the flange'S when said projection is screwed i into the `bushing 6, and assist in` making or insuring a tight joint between the nipple andV the combination bushing, and, therefore, be` Y tween the tubes 4'and2. I j

Withthe spring -located on the tube 4 somedistance from the end of said tube which is to receive the nipple 9, the shouldered` part 11 of said nipple is inserted in said tube end and the nipple is forced inwardly until said tube end encounters the flange 12.

The'spring 5 is now forced toward theend of the tube 4 in which the nipplev9 is received, and over the portion thereof that einbraces said'nipple-until the flange 12 is en-v Vnently attached to said tube.

`lZVhen it is desiredtofconnect the tube-4 with the tube 2, it is simply necessary to screw the projectionlOinto the bushing 6 as far as the flange l2 permits. The brush is then ready for use4 for., shower purposes. When it is desired to disconnect the tube 4 from the tube 2, as in the event the brush is to be used for other than shower purposes, or independently. and separately from said tube, theY nipple projection is unscrewed from the bushing 6. The couplingand uncoupling ofthe tubular 'parts` and members are thus accomplished in an easy, convenient,l ancL expeditious manner, and lwithout stretching and wearing the tube 4' at the' terminal where connection is made with the tube 2.

Although weprefer to make the bushing` 6 of metal, it might `be made of hard-rubber orpother material which is stable under teniperature changes, and-not liable to shrink or expand to an appreciable extent. Y

` Itis conceivablethat minor changesin the shape, size, construction, and arrangementof some or all of the parts of this connection may be made,vwithout departing from the spirit of our invention or exceeding the scope ofV what is claimed.

Vhat weyclaini as our invention, and desire to securebyLetters Patent, is-H The combination, in a connection' of the class described, of a discharge tube of comparat'ively fragile material, abushing of com-v paratively fragile material extending a short distance into said tube at one end, said bushing having a wall of uniform thickness in said tube, a clear passage therethrough from end to end, and an exterior flangecovering the contiguous end of said tube, and being Vcemented to the tube, and a thin interiorly screw-threaded bushing, of .material that is comparatively Vstable under changes, in said first-named bushing and cemented thereto, and in vpartwithin the coiifines of said tube, said Vsecond-named bushing havingclear passage therethrough from end to end, whereby the terminal of said tube which is thus provided withpthe two bushings is reenforced and strengthened, the tube pas-y sage'isv somewhat Vcoifistricted, and said tube is provided with means for attaching and detaching a nipple to and from the same.
